At a glance

CVE-2024-13528 is a high-severity Improper Authentication vulnerability in the Customer Email Verification for WooCommerce WordPress plugin, affecting versions <= 2.9.5. It carries a CVSS score of 7.5 (reachable over the network; high confidentiality, integrity, availability impact). The issue is fixed in version 2.9.6; sites on affected versions should update now. Disclosed February 2025, reported by wesley (wcraft).

Vulnerability Overview

The Customer Email Verification for WooCommerce plugin for WordPress is vulnerable to Authentication Bypass in all versions up to, and including, 2.9.5. This is due to the presence of a shortcode that will generate a confirmation link with a placeholder email. This makes it possible for authenticated attackers, with Contributor-level access and above, to generate a verification link for any unverified user and log into the account. The 'Fine tune placement' option must be enabled in the plugin settings in order to exploit the vulnerability.

Technical Analysis

The vector marks this flaw as remotely reachable over the network, and no interaction from a victim user. A successful exploit has high impact on confidentiality, integrity, availability — full site compromise territory.

CWE-287: Improper Authentication

Reaching this weakness in Customer Email Verification for WooCommerce <= 2.9.5 takes a caller who can reach the endpoint. Improper authentication means the mechanism that proves who a caller is can be satisfied without the secret it was supposed to require.

An attacker authenticates as another user — administrators included — without ever knowing a password, so password policies and login rate limits never come into play. For Customer Email Verification for WooCommerce the fix is 2.9.6: builds <= 2.9.5 are affected, anything from 2.9.6 onward is not.

Remediation

Update to version 2.9.6, or a newer patched version

How does WordSec protect against this?

Because it turns on account access, WordSec's login security is the relevant layer: role-based two-factor, captcha and brute-force limits raise the cost of getting the account this needs. None of that substitutes for the fix: Customer Email Verification for WooCommerce 2.9.6 closes this, and updating the plugin is the step that ends it.
